GENERAL

1. SYSTEM DESCRIPTION

38LZA & 40LZA is for use in commercial split systems. 40LZA080, 100 & 125 are designed for horizontal at theceiling. 40LZA150 & 200 are capable for horizontal and vertical (upflow) installation on floor or at ceiling. Theseindoor units are applied with ductwork.

40LZA150 & 200 are dual circuit fan coil units. These indoor units can be coupled with either single or doubleair-cooled condenser unit - 38LZA. For 40LZA150, it can be coupled with 38LZA150 or 2 units of 38LZA080.For 40LZA200, it can be coupled with 38LZA200 or 2 units of 38LZA100.

2. PRODUCT

• Indoor Unit - 40LZA

Factory installed refrigerant metering device, Thermostatic Expansion Valves, cooling coil, 1" washable airfilter, prepainted drain pan and galvanized steel panels. Units are insulated internally with 12.7mmpolyurethane and also equipped with tubes connection of liquid and suction line. 40LZA150 & 200 havedual circuit with double connection.

The non-ferrous direct expansion coil is constructed with Carrier's Lanced Sine Wave aluminium plate finsmechanically bonded to 3/8" (9.5mm) copper grooved tubes with all joints brazed. The fin density is not lessthan 589 fins per meter.

Draw-thru fan shall be centrifugal forward curve, direct driven by permanent split capacitor motor (40LZA080,100 & 125), belt driven by a totally enclosed fan cooled motor (40LZA150 & 200).

• Outdoor Unit - 38LZA

Draw-thru, consist of single propeller fan, direct driven. Metal fan guard is installed at the front of thepropeller fan where it offers quick access and easy maintenance. The motor has inherent protection andpermanently lubricated.

The compressor is fully hermetic scroll type and equipped with oil level sight glass, rubber anti-vibrationmounting and belt type crankcase heater (UL & CE marked). Belt type crankcase heater should be factoryinstalled. The power input is 230V-1Ph-50Hz supply.

The control shall be factory wired and located in a separate enclosure, safety device is high and low pressureswitches and compressor internal or external overload. Unit wiring shall incorporate a start delay timer toprevent short cycling of compressor if power is interrupted. Definite purpose contactor is energizing thecompressor and fan operation.

Direct Expansion coil is aluminium plate fins with Carrier's Lanced Sine Wave pattern mechanically bondedto seamless 3/8" copper tube.

Casing shall be fully weather-proofed for outdoor installation. The panels shall be manufactured from heavygauge galvanized steel, phosphates and finished in baked enamel paint.

3. INSTALLATION

Furnish and install fan coil and condenser units in the location and manner shown in IOM manual. For 40LZA080,100 & 125 power supply is 230V-1PH-50Hz. For 40LZA150, 200 and 38LZA080, 100, 125, 150 & 200 powersupply is 400V-3Ph-50Hz. These models are designed for use with Refrigerant R-22 only.

Notes:1. Direct interpolation is permissible. Do not extrapolate.2. Capacity included indoor fan motor heat.3. SHG is based on 27°C DB / 19°C WB for air entering indoor coil. At any other temperature, correct the SHG

reading from the table of cooling capacity as below:

Eg. BELOW 27°C, SUBTRACT (CF x l /s) from SHG givenABOVE 27°C, ADD (CF x l/s ) from SHG given

where, A: Actual temperature db °CCF: Correction Factor

4. "INPUT" includes both outdoor and indoor unit.5. Capacities based on 7.5m long tubing with 1m level difference and applicable to outdoor unit voltage range of

342V to 415V.6. Operating limit: Entering air temperature to condenser should be in the range of 25.0°C to 46.0°C (75.0°F to 115.0°F)

Not recommended to operate outside this range.

NOT RECOMMENDED FOR SUSTAINED OPERATION IN THIS REGION.
